The drying of soaps, and of wetting agents such as aliphatic sulphates and sulphonates and alkyl aryl sulphonates, is referred to.  Also the drying of amino acids, proteins (e.g.eggs), and salts (carbonates and borates).  In the evaporator shown in Fig. 1, the solution is sprayed into shell 10 through circularly-arranged nozzles 13, and hot air is introduced through conduit 11.  Partially-dried particles and air are discharged into chamber 18 through a hole in the base of frusto-conical section 14.  The air changes direction and passes through annular space 16 and ducts 19 to outlet-conduit 12, but the particles travel on downwardly to deflecting wall 23.  The particles then pass through opening 22, and flow over a series of annular baffles to conveyer 20.  While falling between the baffles, the particles are dried and cooled by air at atmospheric or room temperature flowing transversely through them; the cooling streams being induced by the application of suction at the lower end of pipe 30.  Cooling air enters the pipe 30 through openings 32 and through the open upper end 31; turbulence in cone 23 being prevented by four vanes 33 extending from the pipe to the inner wall of the cone.  Fig. 3 shows another embodiment of the final drying and cooling system. In this case the particles flow over a series of spaced conical baffles 133, 34, 35, positioned within the outlet of chamber 18; and the cooling air is sucked, through spaces 36, 37 and transversely through the falling particles, into chamber 18 by means of a suction-device attached to conduit 12 (Fig. 1).

Title: A process for the production of iron or steel
IPC: C21C1/00
Filed: 1953-03-03
Abstract: In the production and refining of iron and steel the melt is maintained substantially free from substances containing aluminium or aluminium compounds during the whole process, e.g. by treating or storing the melt in vessels having linings containing less than 0.1 per cent of aluminium or aluminium compounds.  The melt may be left to stand for an extended period of time at high temperatures to effect segregation of any such compounds which may be present in the metal.  Where the linings of the vessels used contain excessive amounts of such compounds their presence in the melt may be avoided by adding to the slag or melt material having a greater affinity for oxygen than has aluminium in the prevailing conditions.  This material may contain or consist of magnesium, cerium or calcium and may be added by injection using e.g. lances or nozzles.
